| Description | Despite decades of searching, observationally confirmed cases of dual AGNs are extremely rare, and most have been discovered serendipitously. Using the all-sky WISE survey, we identified a population of over 200 interacting galaxies that display extreme red mid-IR colors thus far exclusively associated in extragalactic sources with powerful AGNs, despite showing no signatures of activity in the optical. We were recently awarded short exposures by Chandra to observe the 15 brightest MIR-selected dual AGN candidates with separations of a few kiloparsecs, of which 8 display two nuclear X-ray point sources suggestive of dual AGNs. We propose follow-up XMM+NuSTAR observations of two of the brightest targets to constrain the intrinsic absorption of the systems and characterize the nature of the nuclear source. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
